Lamm Industries M 2.2 Mono Blocs

Lamm Model M2.2 is the most powerful amplifier in the line of LAMM hybrid and solid-state audio equipment. It is one of the best creations of its designer’s professional career — a result of years of intensive research directed at attaining the most accurate reproduction of recorded music.

The M2.2 is a masterful blend of design and engineering simplicity. It assures the recreation of a three dimensional sound stage in the home, recording studio, etc. without boundaries and limitations. A distinctive feature of the M2.2 is the extraordinary transparency and localization of perceived sound. It is a pure class A amplifier, with the exception of the output stage which operates in a highly biased A/AB mode.

The M2.2 incorporates high-speed MOS-FET transistors in the output stage with no overall feedback. Special switch-selectable biasing circuit maintains the optimal idle current of the output stage for all load conditions between 1-16 Ohms. It is a hybrid design with the one specially selected 6922 vacuum triode.

These RARELY ever come up for sale and and have been in my system since I bought them in 2007 driving my Magnepan 3.6r loudspeakers.

220 Watts into 8 Ohms (41 Watts Class A operation). 
440 Watts into 4 Ohms (20.5 Watts Class A operation). 
700 Watts into 2 Ohms (10.25 Watts Class A operation). 
900 Watts into 1 Ohm (5.125 Watts Class A operation).

The M2.2 can drive any known speaker.  The harmonic structure remains intact regardless of the speaker load, while the extreme clarity is maintained at all power levels. 

As most reviewers have concluded, these are the closest to the best in the world, if there is such a thing. 

..I don’t know if the Lamm M2.2 is the best power amplifier in the world, because I have not heard all the power amplifiers out there. But, I can say that it is one of the best audio products I have ever heard, period. It is priced like a Maserati, has conservative looks as does a Maserati, and performs at a level like a Maserati. I simply can’t imagine anything sounding better than this.
